DOUBLE-SEAMING MACHINE.

Patented Mar. 10, 19141:. Renewed February 3, 1914` Serial No. 816,334.

To ZZ 'whom t may conc/era .Be it known that we, James Josemi GiurmN, a citizen of the United States of Amer ica, and ay resident of the city of San Francisco, in the State of California, United States of America, (whose postollice address is 1131 Shotwell street, in the said city of San Francisco, but who is temperarily residing at 1 Garden street, South Yarra, a suburb of the city of Melbourne, in the county of Bourke, State of Victoria, Coninmnwcalth of Australim) and GORDON ivlorrmr Peacock, a subject of the King of Great Britain and Ireland, and a resident of 11 Garden street, South Yarra aforesaid, have invented certain new and useful lmprovements Relating to Double *Seaming Machines, of which the following is a specification.

This invention relates to double seaming machines of the kind having a plurality of seaming heads or stations, such as set forth in our application Serial No. ($111,698, filed March 15th, 1911.

The objects of the invention are to provide simple, continuous and positive means for feeding the cans from one common source to a multiplicity of seaming devices; and also for removing the seamed cans from said devices in an analogous manner, while always providing for the preservation of the cans from possible injury.

Referring to the accompanying drawings from the several figures of which details and parts have Occasionally been omitted or broken away for convenience of illustri tionz-Figure 1 is a front view of a double lseaming machine to which the present invention is applied. Fig. 2 is a plan of Fig. 1. Fig. 3 is a plan of the can feeding table. Fig. elf is a longitudinal section of Fig. 3 on line X. Fig. is a cross section of Fig. 3 on line lV.

Fig. 11 is an enlarged cross section of the slide modified. in structure and operation. Fig. 12 is a side elevation of a moving member of the modified slide. F ig. 13 isa. plan of Fig. 12.

The double seaming machine to which the invention is applied is preferably constructed as described in our pending application Serial No. 614,498, and is provided with a number of similar but independently controlled can seaining mechanism 95 arranged in a longitudinal series, and the present invention provides means for :feeding cans to each seaming mechanism to be seamed thereby, and for removing the seamed cans.

The invention includes the provision at the front of the machine framework T of a horizontal feed table having at its inner side a guide flange 8 having openings 9 opposite each seaming mechanism. At each side of each opening 9, and projecting thereinto may be a plate spring 9^. Upon the top of the table parallel with the [lange S is a longitudinal series of guards or guides 10 separated by openings 11. Between the guides S and 1() passes a wide feed belt 12. At the outer edge of the table is a guide flange 13, and between the guides 1() and 13 passes a return belt 19A. The guide 13 is provided near one end of the table with an inwardly curved portion 13 having' beneath it a slot or passageway to aeconnnodale the belt C19-t, and adjoining the portion 13 is a return opening 11A. Attached to the guide pieces 8, above the feed belt 12, inner dellecting guides lft are provided with grooves 15 to accommodate a slide bar 127 hereinafter referred to. Attached to the guides 10, above the feed belt 12, are outer dellecting guides 16. At one end of the table is a guide piece consisting of an inner deliccting portion 17 and an outer dellecting portion 1.8 attached to the adjacent guides 8 and 10. The feed belt 12 moves in the direction indicated by the arrow Fig. 2. and return belt 153A moves in the reverse directions; these belts may be driven by any suitable means. As imlieated in the drawings the belt 12 is driven by a. pulley 12 on a shaft 12b driven by belt 1 2C from a pulley 12d on a shaft 31, which drives by means of gearsl 32 and 5i' the shaft 58. rlhe belt 13A is driven by a pulley 131L on a shaft 153" driven by a. pulley 13 and cross belt 13d from a pulley 13c on shaft 31. Attached to the inner edge of the table adjacent each of the openings 9 is a can rest or cross 20.

At one end of the main frame is a verti cal shaft 5S which is driven by bevel gearing from the longitudinal main shaftas indicated in the drawings. 0n shaft 58, is a bor; cam 59 engaged by a roller G1 on the short arm G2 of a bell crank lever which latter is pivoted at G3 on the framework. To the long arm 6a of the bell crank lever is pivoted one end of al link 65 to the other end of which is pivoted a lever G6, attached to a rocking shaft. G7. Loosely surrounding said rocking shaft 67 are a series of levers G8 each provided in its boss with a round hole G9. Upon the said rocking shaft are a series of collars each of which adjoins one of the levers 68. Each collar is loose upon the said shaft. ln the rocking shaft beneath each collar is a recess 71 in which lies a key 7 e pivoted at one end by pivot pin 72, and resting at its other end on a spring 7 3 in the recess. 1n each collar 70 is a hole in which is placed a headed pin 7 6, behind which is a spring 77, the tension of which may be adjusted by a screw 7 8 tapped into the said hole 7 A slide consisting of two sido members 127 united by a bridge piece 123 is att-ached by a connecting rod 125 and pivot pin 126 to each of the levers (33. On each side menu ber 127 are a series of pins 129 upon each of which is pivoted an arm 130. Each arm is controlled by a spring 131. The arms on each member 127 that correspond in situation form working pairs. The springs 131A of the second pair of arms are stronger than their fellows. Each side member is provided with a. series of stops 132, one for each arm 130, and each arm has a limiting protuberance 133 adapted to engage with its relative stop 132.

The cycle of operations with this invention is as follows: The cans to be fed are placed upon the feed belt 12 and traveling therewith come into contact either with inner detlecting guides 111 or outer deflecting guides 16, dependent upon the position of the cans upon the belt. If a can contacts with an inner dei'iecting guide lil it will be retained thereby and any can which may be immediately following it will pass on and be retained by the next guide 14;. Should a can contact with an outer deflecting guide 1G the latter will direct the can toward the inner guides. Should all the inner guides 14: retain cans simultaneously, the other cans then being fed by the belt 12 will simply pass by each inner and outer deflecting guide 1st and 1G successively and be ultimately directed by the end guide 13 onto the return belt 13A and returned thereby to the guide portion 13B of guide 13, by which it will be directed through the opening 11A ont-o belt 12 to be re-fed. Should a block occur at any of the guides 111 the cans being fed can pass through the openings 11 onto the return belt 13A. rllhus the cans cannot be injured by the feed and the feed is con- Vthen raised and presented to the seaming devices as described in our aforesaid application, and after the head or closing disk is seamed to the can body the slide is shifted to remove the can. The slide is properly .shifted by the roller 61 following the sinu- `ous groove of the boX cam 59 and actua-ting the bell crank lever which by the link 65 and lever 66 operates the rocking shaft 67 and levers 63, each lever 63 being engaged with its relative slide by its respective connecting rod 125. As each slide moves, for example, toward the openings 9 its arms 130 pass the can then upon the cross 20, said arms 130 swinging outwardly to pass the can but, resuming their inward positions when past it on accountof the springs 131. As the slides recede by the action of the mechanism above mentioned the relative arms 130 coming up behind the can remove it from the cross 20. The slides may deliver the cans to a sheet conveyer (not shown) or any other device for discharging them from the machine. At the time when a can is being removed from a cross 20, the first pair of arms on the slides which have already engaged a can within the relative inner deflecting guide 141-, move such can inward, and therefore while one can is being removed from its cross, another is being moved toward the said cross 20. When the latter can'is brought over the cross the slide again moves toward the openings 9, the first pair of arms 130 engage a new can, and another pair of arms 130 come into posi tion behind the can on the cross. The first can is then double seamed, and as soon as that operation is completed, the slide moves inward again removing the seamed can and placing another can in positionv as already explained. The second pair of arms 130, having t-he stronger springs 131A, prevent the possibility of a can being inadvertently moved toward its cross by any unforeseen circumstances, such as the pressure of cans being fed moved forward by the belt 12.

1n some cases the bridge piece 12S may be dispensed with and theA side me aber 127 nearest the feed end of the machine left stationary, while only the member 127 to which the connecting rod 125 is attached moves (see Figs. 11-13). This member has at its end adjacent the feed table a finger 135 pivoted on a pin 134; having an engagementend 13G. Pivoted at 137 to the side of the moving member 127 is a inger operating dcvice 133 having a slot 139 through which passes a guide pin 11.10 attached to the side of the moving member'. At one end ot the device 138 is a finger 1111 having on its lower side an inclined lace 142; and at the other end ot the said device 138 is a stop lug 1-13. Upstanding from the framework 7 adjacent the moving member 127 is a stop 11151. When the rising and falling finger are used the plate springs 9^ can be dispensed with and the springs 131A be of the same strength as their fellows. When. using the linger 135 only one member 127 is operated, its fellow member remaining stationary. As the member 127 to which the linger is pivoted recedes the protuberance 143 strikes the stop 1411 moving the device 13S upon its pivot pin 137. The protuberance 1411 then descends upon the ringer engagement end 13G below it and elevates the said finger as shown in the drawings (Figs. 1143). The slide member 127 now advances toward its inner detlecting guide 1K1 the inclined face 1112 engaging the said guide and thereby7 again moving the device 138. This, however, elevates the protuberance 1411 from the lfinger engagement end 136 permitting the finger 135 to ft'all into a horizontal position by gravity. The finger is now behind the can within the del'lecting guide 1-/1 and as the slide again recedes moves the can toward the seaming head. When the protuberanee 143 and stop 1111 again engage, the linger is elevated into a vertical position as already described. The arms 130 during these operations move to allow the cans to pass as formerly. Should. any obstruction occur to the slide such as an inadvertent accumulation of cans the said slide upon reaching the same and encountering unnatural opposed pressure is automatically thrown out ot' Igear as long as the obstruction exists thereby preventing a can or cans being injured. lt automatically re-commences its operations however when the obstruction is removed. This is effected by the relative pin 7G, the point or nose ot which is held within the pin hole (59 oit the relative lever (SS by the respective spring 77 the tension oit which overcome when an obstruction is met, thereby permitting the pin 7 G to recede :irom the hole (39 and disengaging the lever 68 from the collar which actuates it.

Each collar 70 is actuated by the rocking sha'lt through the agency ot the relative pivoted key 741. rlhe key 711 being` pivoted and spring controlled as shown, by depressing such key 7-1 and moving the respective collar 70 along the sha'tt out of engagement with its relative lever G8, any imlividual slide may be eut out of operation without interfering with the action ot' the others.
